SPECIFICATION forming part of Letters Patent N 0. 670,111, dated March 19, 1901.

Application filed July 28, 1900.

T0 mil whom it may concern.-

Be it known that I, CHARLES PHELPS, a citizen of the United States, residing at Oskaloosa, in the county of Mahaska and State of Iowa, have invented certain new and useful Improvements in Sheet-Metal Radiators, of which the following is a specification.

The object of this invention is to provide a two-piece internal brace for sheet-metal radiator-sections to surround the openings in the section through which connection is made.

with adjacent radiator-sections, said pieces to be so designed as to be capable of being cast without coring and when disposed within a radiator-section to provide circulatingopenings from the interior of the brace to the interior of the radiator-section and at the same time to provide smooth flat ends to engage the sides of the radiator-section.

My invention consists in certain details in the construction, arrangement, and combination of the brace with the radiator-section, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 shows in perspective one of the mating pieces of the two-part brace. Fig. 2 shows a vertical central sectional View of the lower portion of a sheet-metal radiator having my improved brace in position therein.

Referring to the accompanying drawings, I have used the reference-numeral 10 to indicate that portion of the sheet-metal radiator shown. In the sides of the sheet-metal radiator, near its lower end, the annular shoulders 11 are formed, and 12 indicates the openings in the sides through which connection is had with adjacent radiator-sections. The brace is composed of two identical parts,- which may be cast from the same pattern. Each part comprises an annular ring 13, having a smooth flat face 14 at one end and at the other end having a series of projections 15, the outer ends of which are beveled at 16 for purposes hereinafter made clear. These projections 15 are made considerably narrower than the spaces between the projections, and, furthermore, the edge of the ring 14, between the projections 15, is beveled at 17 for purposes hereinafter made clear.

In practical use and assuming that two Serial No. 25,114. (No model.)

identical parts formed as shown in Fig. 1 are placed together on the interior of a radiator-section, as shown in Fig. 2, with the smooth ends outwardly and the projections of one ring entering the interdental spaces a rotation of one ring with relation to the other and will securely center the projections of one ring in the interdental spaces of the other ring, thus providing circulating-openings from the interior of the brace outwardly into the radiator-section.

Having thus described my invention, What I claim, and desire to secure by Letters Patent of the United States therefor, is

1. An internal brace for sheet-metal radiator-sections, comprising two like parts, each part comprising an annular ring having on one face a series of projections of a size considerably less than that of the spaces between the projections so that when placed together, the projections of one enter between the projections of the other and rest upon the inner edge of its ring and spaces are formed between the projections for the circulation of the heating medium, for the purposes stated.

2. An internal brace for sheet-metal radiators, comprising two parts of identical construction, each part comprising an annular ring with one smooth end and a series of projections of equal length, on the other end, said projections being of a size considerably less than that of the spaces between the projections so that when placed together, the projections of one enter between the projections of the other and rest upon the inner edge of its ring and spaces are formed between the projections for the circulation of the heating medium, for the purposes stated.

3. An internal brace for sheet-metal radiators, comprising two parts of identical construction, each part comprising an annular ring with one smooth end and a series of pro jections 15 on the other end, said projections being of equal length, and beveled at their outer ends, and said projections being of a size considerably less than that of the spaces between them, and beveled surfaces 17 on I medium, substantially as, and for the pmthe end of the ring, between the said projecposes stated.

tions so that when placed together, the proi 1 jections of one enter between the projections CHARLES PHELPET of the other and rest upon the inner edge of Witnesses:

its ring and spaces are formed between the J. RALPH ORWIG,

projections for the circulation of the heating ANDREW ENGLE.
